Fibre optic cable EFB Elektronik O0350.3-1.2 3 m 2x LC Yellow

The EFB Elektronik O0350.3-1.2 3 m 2x LC Yellow is an OS2 single-mode fibre optic patch cable designed for reliable point-to-point connections in telecom and data centre environments. With a 9 µm core diameter and LC duplex connectors on each end, the cable supports full duplex transmission and is intended to provide low attenuation and stable performance over the specified link length. The yellow jacket provides industry-standard colour coding for single-mode installations and helps with cable identification and management.

Advantages

This 3 m fibre cable offers precise optical geometry and standard LC duplex termination for easy mating with LC ports on transceivers and patch panels. The OS2 single-mode design and 9 µm core minimise modal dispersion and attenuation for long-distance or high-speed links within its intended application. The yellow outer sheath improves visibility in structured cabling systems and simplifies tracing and maintenance tasks.

Suitable for

• Connecting single-mode transceivers, SFP/SFP+ modules and patch panels
• Short in-rack or between-rack links in data centres and server rooms
• Telecom access links and building backbone segments
• Environments requiring standard colour-coded single-mode cabling

Key specifications

• Fibre type: OS2 single-mode
• Core diameter: 9 µm
• Length: 3 m
• Connector type: LC duplex on both ends (2x LC)
• Polarity: full duplex
• Jacket colour: yellow

How to use

Inspect connector endfaces for cleanliness before installation and clean with appropriate fibre cleaning tools if required. Plug the LC duplex connectors into matching LC ports on transceivers, patch panels or equipment, ensuring correct alignment and secure seating. Route the cable following standard bend-radius and strain-relief practices to avoid microbending and attenuation increases. Verify link performance with a suitable optical test instrument after installation.

Recommendations

Store and handle the cable to avoid tight bends or crushing; maintain the manufacturer-recommended minimum bend radius. Use dust caps when connectors are not connected and perform endface cleaning before mating to preserve optical performance. For critical links, validate loss with an optical power meter or certification tester.
